9 Claims.

"This 'invention relates tov lubricators for car journals. The invention has particular reference to lubricators that, employ a wick for carryinglu- 'bricant tov the axle,A and a spring pressedwick; izholder serving to yieldably press the upper end` of the rwick against the axle.

In certain journal boxes the space between the axle and `sidewall ofthe journal'box is .rather limited, andlpne` of the objects of this invention Qdisrto providegalubricator Ywhichis capable of func tioninfgl properly in such limited space.4

Another object is to simplify and to reduce l. thehumber of fpartsof thedevice. Another ob-` jectis; toprovide a wick holder inthe form f of twohingedly vconnected leaves, oneof which is., slidablymounted, and the other of whiehis springy pressedV toward. the axle Wherebr to press the upperend ofv, the wick, against it. I.

, .Referring to-said drawing, the Vref erence character; Idesignates a journal box of conventional form, fin whichisrcontained the bearing brass II that 'blarsfuponzthe caraxle I2. In the bottom of the'uournal boxis` a well 9 in which is con tainedaf `quantity 'ofa lubricant. Y

Bolted or otherwise rigidly secured to either Wall I3 of the journal box is a supporting bar I4, having a horizontal part I5, which is offset slightly from the side of thewall. The supporting bar is located somewhat below the axis of the axle;

Slidably mounted on the offset part of the supporting bar is a wick holder I 6 desirably composed of two struck up sheet metal leaves I1, I8, hingedly connected together by a horizontally extending pintle 8, and urged apart by a spring and arms 2|,` 22 engaging thefrespective leaves.

fragments- (c1. `sos-ss) Desirably the spring device I9 is composed of a single piece Yof resilient wire, With the two coils spaced apart and the two arms 22 connected by the part 23. 'I'he exact form of spring device;` however, is not material to the invention, broadly considered.

The metal of the leafY I1 is bent up along its upper end to provide a sleeve 24, which is slidably mounted on the supporting bar, and the lower part of the leaf I1 is notched to form two spaced hinge ears25, 25, that are bent up to provide the apertures for the pintle 8. 'I'he overlapping parts of the. leaf are spotwelded together. The leaf is bentupon itself along a horizontal line between the sleeve and pintle, whereby the hinge Vears 25 are made to incline toward the axle, thereby bringing the lower ends of the leaves within the spacev formed by the curved lower'wall of the journal box.

The leaf I8 comprises a horizontal, channeled pressure plate 26, from which extends hinge ears 21 that are bent up to provide apertures for the,k pintle. The bent up parts are spotwelded to-f gether asshown. The upper and lower edge vpor-l tions of the pressureplate 26 are bent back upon themselves to form grooves l, in which is received a wick holding strip 28 that carries the wick 29.' Preferably the pressure plate 26 and strip 28 are bentralong horizontal lines midway between their upper and lower edges to make these parts slightj end, and thegedge of the doubled over part 30 is stitched to the main body of the wick. The wick` holding strip 28 is fastened to the doubled over part 3U by staples 3I, thereby leaving the face of A thewick, which bears against the axle, entirely` free from the staples. The ends of the wickhold` ing strip are formed with tongues 32, bent around the ends of the doubled over part of the wick, and

said ends arek also formed with tongues 34 bent 4 around the ends ofthe pressure plate 26 of the leaf I8 to securely fasten the wick on the. wickholder. 'Ihe Vpressure plate 26 is spaced far enough above the pintle to hold the doubled part o of the wick against the side of the axle.

The pintle may fit loosely inthe bearing apertures of the leaves, thereby permitting the leaf i8 to accommodate itself to any angular position the axle may assume.

The lower end of the wick is submerged in the lubricant and carries the lubricant to the axle by capillary attraction. The spring device yieldably holds the doubled part of the wick against the axle with relatively slight pressure and yields as a result of any sidewise movement of the axle in the box. The entire wickholder being slidably mounted on the supporting bar, it is free to shift back and forth along with any endwise movement of the axle relative to the journal box.

It is to be observed that by reason of the shape and construction of the wickholder, the lubricator occupies but little space and can occupy an extraordinary narrow space between the side wall of a journal box and the axle therein, and will function properly despite such narrow space. There are no intervening parts between the swingable wickholding leaf and the supporting leaf that prevent the wickholding leaf from assuming a j position contiguous with the supporting leaf.

The lubricator may, of course, be used in any situation where lubrication of an axle is required; its use is not to be understood as limited to railway car axles.

I claim as new and desire to secure by Letters Patent:

1. A car journal lubricator, comprising in combination, a supporting bar arranged to be supported in a horizontal position on a wall of a journal box in close proximity thereto, a leaf slidably mounted on said supporting bar, a swingable leaf hingedly mounted on the first mentioned leaf on a horizontal axis located below the supporting bar, a wick, means to removably secure the wick to the upper part of the swingable leaf, and yieldable means to urge said leaves apart and therewith press the upper end of the Wick against an axle journaled in the journal box.
